def set_optimized_parameters(rotor, optimization_problem):
"""
Appends parameters of optimized rotor to input rotor data structure.
Parameters
----------
rotor : RCAIDE.Library.Components.Powertrain.Converters.Rotor
Rotor component to be updated with optimized parameters
optimization_problem : RCAIDE.Framework.Optimization.Common.Nexus
Optimization problem with results and optimized rotor configurations
Returns
-------
rotor : RCAIDE.Library.Components.Powertrain.Converters.Rotor
Updated rotor with optimized parameters
Notes
-----
This function transfers the optimized rotor parameters from the optimization results
to the input rotor data structure. It copies geometric properties such as chord and
twist distributions, as well as performance metrics for different flight conditions.
The function updates the following parameters:
- Geometric properties:
- chord_distribution
- twist_distribution
- max_thickness_distribution
- radius_distribution
- number_of_blades
- mid_chord_alignment
- thickness_to_chord
- blade_solidity
- Hover performance metrics:
- design_power (if not specified)
- design_thrust (if not specified)
- design_torque
- design_angular_velocity
- design_Cl
- design_thrust_coefficient
- design_power_coefficient
- design_SPL_dBA
- design_blade_pitch_command
- OEI (One Engine Inoperative) performance metrics:
- design_thrust
- design_power
- design_torque
- design_angular_velocity
- design_blade_pitch_command
- Cruise performance metrics (for prop-rotors only):
- design_power (if not specified)
- design_thrust (if not specified)
- design_torque
- design_angular_velocity
- design_Cl
- design_thrust_coefficient
- design_power_coefficient
- design_SPL_dBA
- design_blade_pitch_command
**Major Assumptions**
* Default noise measurements are taken 135 degrees from rotor plane
